Antlia

The Antlia IR Pass 685nm filter is an absorption filter that allows infrared light with wavelengths of more than 685nm to pass through. It nicely complements the Antlia 850nm IR-Pass filter.

The Antlia IR Pass 850nm filter is an absorption filter that allows infrared light with wavelengths of more than 850nm to pass through. It nicely complements the Antlia 685nm IR-Pass filter.

Antlia LRGB series are high quality colour filters specially designed for deep space photography of black and white cameras. Available in 1.25", 2", 31mm and 36mm formats.

The Antlia H-Alpha (Ha) 3.0nm filter is suitable for imaging H-Alpha emissions from nebulae, planetary nebulae and supernova remnants.

The Antlia SII 3.0nm filter is suitable for imaging SII emissions from nebulae, planetary nebulae and supernova remnants.
The 3.0nm bandwidth delivers a high transmission at a center wavelength of 671.6nm.
